LIQUID-DRAVVING DEVICE.

SPECIFICATION forming part of Letters Patent No. 679,201, dated July 28,1901.

Application led July 20, 1900.

To all whom t may concern.-

Be it known that we, WILLIAM'ALLIsoN and PATRICK H. KEEFE, citizens ofthe United States of America, residing at Pittsburg, in the county ofAllegheny and State of Penn- Sylvania, have invented certain new anduseful Improvements in Liquid-DrawingDevices, of which the following isa specification, reference being had therein to the accompanyingdrawings.

This invention relates to certain new and useful improvements inliquid-,drawing devices, and more particularly to beer-tapping devices.

The invention has for its object the provision of novel means wherebybeer or other malt liquors may be efficiently drawn from a barrel or kegwithout incurring a loss of the carbonated gases; furthermore, toproduce a device that will be extremely simple in its construction,strong, durable, and comparatively inexpensive to manufacture.

The present invention further aims to construct an apparatus of theabove-described class that may be readily attached to a barrel or kegand easily removed therefrom; furthermore, a device that may be operatedin conjunction with an air-pump or any suitable air-pressure tankusually employed for this purpose.

With the above and other objects in View the herein-described inventionfinally consists in certain novel features of construction, combination,and arrangement of parts to be hereinafter more particularly described,and specically pointed out in the claim.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, and whereinlike numerals of reference indicate like parts throughout the severalviews, in which- Figure l is a vertical sectional view of a barrel withour improved apparatus attached thereto. Fig. 2 is a similar enlargedview of the apparatus and a portion of the barrel. Fig. 3 is a detailView of the air-valve. Fig. 4 is a top plan view of the same. Fig. 5 isa vertical sectional view of the same.

In the drawings the reference-numeral 1 indicates the barrel or keg,which is provided Serial No. 24,316. (No model.)

with the usual outlet 2, arranged in the head of the barrel.

The reference-numeral3 indicates a collar, carrying on its peripheryscrew-threads 4t. This collar is also interiorly screw-threaded, asshown at 5, and a flange 6 extends outwardly from the periphery, thelatter being formed integral with the collar. A contracted opening 7 isarranged in the lower portion of the collar, the latter being adapted toreceive the beer-discharge pipe 8, extending downwardly into the barrel.This pipe 8 carries a removable collar 9, the latter being exteriorlyscrew-threaded and adapted to engage the iuteriorly-screw-threadedportion 5 of the collar 3. A gasket or flexible washer 10 is interiorlyarranged in the collar 3 above the contracted opeuin g and the lowerextremity of the collar 9. To the upper end of the dischargepipe 8 isrigidly secured a twin coupling 11, forming on one side an upwardextension 12 of the beer-discharge, and on its one side an air-inlet 13,extending upwardly at an angle and formed integral with the said upwardextension 12, carries an enlarged portion 14, having seated therein avalve 15, carrying an operating-handle 16. The upper end of theextension 12 is slightly iianged and is provided with exteriorscrew-threads 17, which are adapted to receive a cap 18, the latter inturn being interiorly screw-threaded, as shown at 19, and provided witha central opening 20, the diameter of which is less than the interiordiameter of the extension 12.

A nipple 21 is adapted to snugly iit into the opening 20, said nipplehaving formed integral therewith, on its lower extremity, an annularange 22, which is seated under the cap 18. A washer 23 is interposedbetween the flange 22 and the upper end of the extension. The upper endof the nipple 21 is provided with a flexible tube 24, leading to andconnected with a suitable discharge-faucet.

The air-inlet 13 is provided with an enlarged air-chamber 25,communicating with a contracted air-pipe 26, the latter leading into theextension 12 and downwardly through a portion of the beer-discharge pipe8, terminating into a discharge-port 27, formed in the discharge-pipe 8.The upper end of the air-chamber is exteriorly screw-threaded, as

IOO

shown at 28, and is also interiorly screwthreaded, as indicated by thereference-numeral 29, the latter serving to receive the collapsiblevalve 30, which is formed of a disk 3l, having exterior screw-threads 32and a central opening 33V and carrying a boss 34 atv its lower end, anda contracted neck portion 35 to receive the flexible collapsible tube36. The said tube may be fastened to the neck portion Vby any suitablemeans, such as a band 0r wire 37. The upper face of the disk 31 isformed with a` slot 38, serving' as means to properly seat andadjustlthe Valve within the air-chamber. Thus, if desired, diskshavingvarying capacities may be applied.

An in'teriorly-screwthreaded cap' 39 engages the screw-th reads 28 ofthe air-chamber, said cap having a central opening'40 to receive thenipple 41, carryinganannulartlauge 42, the latterpbeingadapted to t inthe cap 39, a washer -l3 being' interposed betweenthe under face of saidiiange and the end of the air-chamber. e

,'lhereference-n u ineral 44 represents a flexible tube connected to thenipple 4l, said tu be leading to a pump or air-pressure tank, as thecase may be'.

In View of the above detail description of the various parts it isthought a description as to the operation ot' the device is unnecessary.changes may be made in the details of construction without departingfrom the general spirit of our' invention.

Having thus fully described ourI invention,

'what we claim as new, and desire to secu re by Letters Patent, is'- Itwill be noted, however, that various to the upper end of saiddischarge-pipe, an airinlet pipe formed integral with saidupwardlyextending pipe and arranged at an angle thereto, a contractedair-pipe communicating with a contracted air-pipe extending downwardlythrough the beer-discharge pipe into said barrel, a removable diskhaving a centrai opening, a boss arranged on the under side of saiddisk, and a contracted neck portion between said boss and said disk, acollapsible check-valve arranged upon said neck land boss in the'interior upper extension of said air-pipe; a Valve arranged in saidupward extension, exterior s`crew-threads arranged at the upper ends ofsaid upward eX- vtension andVair-pipe, interiorly-screw-threaded capseach having a central opening formed therein' secured-u pon saidscrew-threaded portions, nipples, flanges on said nipples seated in saidscrew-threaded cap, a washerinter- `posed between the under face ofVsaid flanges tures in the presence of two witnesses.
